　　Questions 21 to 25 are based on the following passage:

　　注：1.concentrate 集中注意力 2.第一段交待實驗對象，實驗目的

　　In the first test, each subject sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a grouping of 96. In this simple tests smokers, deprived smokers and non-smokers performed equally well.

　　注：第一句實驗過程即細節，應該速讀，第二句實驗結果

　　The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Non-smokers were faster, but under the stimulation of nicotine , active smokers were faster than deprived smokers.

　　注：1.第一句實驗細節 2.stimulation 刺激

　　In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers.

　　注：committe=do (壞事) commite a crime

　　The fourth test required people to read a passage,
